FILLING-REPLENISHING LOOIVI.

SPECIFICATION forming part of Letters Patent No. 745,363, dated December 1, 1903.

Application led September 8, 1903. Serial No. 172,372. (No model.)

To a/ZZ whom it may concern:

- Be it known that I, ALIDA M. MARooUX, a subject of the King of Great Britain, and a resident of Milford,county of Worcester,State of Massachusetts, haveinvented an Improvementin Filling-Replenishing Looms, of which the following description, in connection-with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates more particularly to looms provided with automatic filling-replenishing mechanismsuch, for instance, as forms the subject-matter of United States Patent No. 529,940-Wherein the shuttle is provided automatically with a fresh supply of filling at the time such replenishment becomesnecessary. Sometimestheshuttlemisthreads after such replenishment, and then a second supply of lling is inserted in the shuttle, and ordinarily the threading is then properly effected. As the misthread occasionally happens .with the insertion of the second filling-supply, it is desirable to thereupon eect the stoppage of the loom in order that the Weaver may ascertain the vcause of the trouble and correct it, for otherwise a -number of filling ychanges might be caused,

emptying the hopper or iilling-feeder.

Devices have been provided to stop the loom automatically if the replenishing mechanism is operated a predetermined number of times in succession, one of such devices being shown in United States Patent No. 727,014, dated May 5, 1908. In such apparatus the loom is stopped automatically after two successive operations of the replenishing mechanism, a misthread occurring on each operation.

My present invention has for its object the simplification and improvement of the means for effecting such automatic stoppage of the loom after a predetermined number of successive operations of the replenishing mechanism.

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a left-hand side elevation of aV sufficient portion of a filling replenishing loom to be understood with one embodiment of my invention applied thereto, the shipper being omitted and the knock-off lever being shown in section. Fig. 2 isa top or plan view of the novel part of the apparatus illustrated in Fig. 1, showing the filling-detector and parts controlled thereby in normal position. Fig. 3 is an enlarged detail, in side elevation, of the mechanism shown in Fig. 2, the nearer side of the detector-slide and its guide or stand being broken out; and Fig. 4c is an opposite side elevation of the device which at the proper time actuates the knock-oit lever to release the shipper.

The lay A3, breast-beam A40, having at one end the usual notched holding-plate N for the shipper S and at the other end supporting the filling-replenishing mechanism, a portion of the filling feeder F thereof being shown in Fig. 1, the controlling rock-shaft d', which governs the operation of the fillingreplenishingmechanism in well-known manner, and the upturned arm d, fast on said rock-shaft and in the outward path of movement of the detector or fork slide, may be -and are all substantially as in said Patent The slide fx, longitudinally movable in a guide f2, transversely secured on the breastbeam, supports in usual manner a filling fork or detectorf, of usual construction, the fork-tail f20 being adapted to coperate with the hook w of the weft-hammer or actuator W upon failure of the filling to tilt the fork.

As is Well known to those skilled in the art, if the fork is not tilted on the detectingpick the slide fx is moved outward and through the arm d rocks the shaft d and eiects a change of filling. side extended forward, as at f'`andjhoo ked to engage the upper overturned end of the arm d, as herein shown, and near its outer end the sides of the slide are provided With upturned ears f4, which sustain a transverse fulcrum or pivot pin f5 for a knock-off latch or dog h. (Very clearly illustrated in Figs. 3 and 4.) The latch or dog is madeas a rather heavy casting, having near its rear end an elongated slot hX, through which the pin The slide has one 9o IOO f5 passes, the dog being hung thereon between the ears f4 and movable longitudinally relatively to the slide, as will be described. The under side of the dog is out away at one side of its longitudinal center and at its front end to present a series of transverse depressions, three being herein shown and indicated at 1, 2, and 3, Figs. 3 and 4, in a stepped arrangement.

A coperating detent, shown as a lug or pin flo, extends inward from the adjacent side of the slidefX and projects into the eutaway part of the dog, said detent being adapted to enter any one of the depressions referred to. Normally the detent coperates with the lowest depression l, the dog then being as far toward the outer end of the slide as it can gofxsee Fig. 8 and also Fig. l) and held up in its highest position. On the opposite side the dog has a depending portion hm, its lower edge being cut away to present two downturned shoulders h h2, also arranged in step formation, the inner shoulder h' being lower than shoulder h2.

As shown in Fig. 2, a knock-oif levern n' is fulcrumed at nx on the breast-beam, to release the shipper from its holding-notch, and, as shown clearly in Figs. l and 2, the arm n normally extends under the dog 72 said arm being provided with an upturned lug or abutment n2, which is in the outward path of movement of the shoulder h when the slide fX is moved out.

With the parts in the position shown in the drawings, let it be supposed that the filling fails and such failure is detected by the detectorf. The latteris not tilted, and the slide fX is moved outward by the weft-hammer, and the extension f3 aetsthrough arm d to turn the rock-shaft df and effect filling replenish ment. At the same time the outward movement of the slide brings the shoulder h of the dog into engagement with the abutment n2 and stops the movement of the dog, the slide continuing to move outward. Such stoppage of the dog disengages the detentf10 from the depression l, and as the slide completes its outward movement said detent will be under the depression 2, so that when the slide posit@ the abutment a2, and if the sud@ is moved out on the next detecting-*pick said abutment will engage the shoulder h2 and stop the dog, while the slide continues to move out, withdrawing the detentfw from depression 2 and positioning it beneath the third and outermost depression 3. Now the slide movesin, the outerend of the dog drops again, and the detent enters said depression 3, so that the abutment n2 will be in the path of the outer end h3 of the part hw of the dog which has been moved inward relatively to the slide as far as it can go, the pin f5 abutting against the outer end of slot hf. If a third outward movement of the slide takes place, the end h3 and abutment n2 engage, and as the slide completes its movement the knock-off lever is turned and the shipper is released to stop the loom. Should the shuttle thread properly after the first or second operation of the repleni'shing mechanism, the weft-hammer will act upon the inner end of the dog to return it to the normal position, (shown in the drawings,) and such resetting of the dog is similarly effected by the wefthammer when the loom is started after it has been stopped as described.

It will be manifest that the number of parts has been materially reduced in my present invention, and a single member (the dog) effects the actuation of the knock-off level' when the slide has been moved out a predetermined number of times in succession. On the rst and second outward movements of the slide the lling-replenishing mechanism is operated, as will be obvious. The horizontal distance between the shoulder h2 and the outer end h3 of the part hw of the latch Vor dog is` made longer than the distance between the shoulders 7L' and h2 in order to provide for the necessary movement of the knock-off lever on the last outward stroke of the slidefx.

My invention is not restricted to the precise construction and arrangement shown and described, as the same may be modified or varied by those skilled in the art without departing from the spirit and scope f my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
